+Series Signature Protein Skimmers have been successfully running aquariums for two decades. Our injector assembly uses a pressure differential to generate a massive quantity and quality of bubbles to maximize protein skimming. Historically, these have been powered by high pressure (high power) pumps, but with the advent of ultra efficient DC powered pumps, these skimmers are more potent and efficient than ever.

Utilized by professional aquarists and organizations worldwide, the MR-4 comes standard with the second injector assembly. The larger body allows for higher flow rates for more demanding systems.
